All the joints are somewhat setose, and the fourth bears a long curved 
seta (the olfactory appendage ?). In the male there is usually a distinct 
geniculation at the fourth and fifth joints, which are more or less swollen 
and coalescent. The posterior antenne are furnished with 5 geniculated 
sete at the extremity, and 2 on the inner margin of the terminal joint ; 
the 4-jointed secondary branch is also furnished with a few sete. Both 
pairs of foot-jaws slender, second pair the strongest. First pair of feet 
with the inner branch consisting of two long joints, the first of which is 
dilated above the middle and bears a plumose seta near its extremity, the 
second is straight, bears a plumose seta on its inner margin, is pectinately 
ciliated on its outer margin and terminates in two claws; the outer branch 
is much shorter, its first joint bears a plumose seta at its apex, the second 
is furnished With two sete at the extremity, one of them being similar to 
the fringed sets of the terminal joint, third joint very short and bearing six 
sete, four of which are somewhat flattened and furnished with terminal 
fringes of close-set cilia, while the other two are longer and plumose. 
Three following pairs of feet almost similar, each branch 8-jointed. Fifth 
pair with a short basal joint, with a seta at each angle of its apex ; second 
joint flattened, ciliated on both margins, and bearing 5 long sete at its apex. 
Caudal segments about as long as broad. Brady states that the fourth and 
fifth abdominal segments are very short, in the specimens examined by me 
the fourth was very short, but the fifth was very much longer, nearly as 
long as broad. He also states that “ the inner tail-setz are nearly as long 
as the body of the animal, outer about half as long, both finely aculeate in 
their entire length." In the specimen figured by me the inner seta is not 
much more than half the length of the body, and this proportional length is 
very general in the individuals examined by me. The animal is usually 
colourless, or according to Brady also “ pale milky-white, often yellowish, 
and sometimes distinctly banded with pale lilac or purple. Length, 
zo~ gy inch (x in. Brady). 
^ Hab. Common in shore kelp and rock-pools near Dunedin ; also on 
kelp in Paterson Inlet. 
An abundant species in European seas: occurring in the littoral 
afd laminarian zones, and often “taken by the tow-net in the open 
gea." 
Genus Scutellidium, Claus. 
Body depressed, subovate. Anterior antennæ 9-jointed, with very short 
median joints ; posterior 8-jointed, the inner branch short, 1- (? 4-) jointed. 
Mandible palp large and complex, bearing numerous stout setiferous fila- 
ments; maxillary palp provided with two very long and stout ciliated 
sete. Both pairs of foot-jaws forming clawed hands. First pair of feet
